關於Struts2的Action的跳轉方式（跳轉到JSP）（跳轉到Action）

success.jsp里：${name }---this is success.jsp

一、跳轉到JSP

請求轉發：http://localhost:8080/struts2action/testAction1!test1?name=tom

index.jsp里：<a href="testAction1!test1?name=tom">請求轉發</a><br>

struts.xml里：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
    <package name="xsl" namespace="/" extends="struts-default">
    
        <action name="testAction1" class="com.xsl.action.TestAction1">
            <!-- 
                type屬性不寫，默認則為type="dispatcher"
                tyoe="redirect"表示重定向到jsp
                type="chain"表示請求轉發至另一個action
             -->
            <result name="test1" type="dispatcher">/success.jsp</result>
            
        </action>
        
    </package>
</struts>    

TestAction1.java里：

package com.xsl.action;

import com.opensymphony.xwork2.ActionSupport;

public class TestAction1 extends ActionSupport {
    private String name;
    public String test1(){
        System.out.println("請求轉發--action1--test1--name--"+name);//請求轉發--action1--test1--name--tom 9         //request.setAttribute("name",name);
        return "test1";
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    
}

success.jsp里顯示：tom---this is success.jsp 

 

重定向：http://localhost:8080/struts2action/success.jsp

index.jsp里：<a href="testAction1!test2?name=jack">重定向</a><br>

    <package name="xsl" namespace="/" extends="global">
    
        <action name="testAction1" class="com.xsl.action.TestAction1">
            <!-- 
                type屬性不寫，默認則為type="dispatcher"
                tyoe="redirect"表示重定向到jsp
                type="chain"表示請求轉發至另一個action
             -->
            <result name="test2" type="redirect">/success.jsp</result>
        </action>
        
    </package>
</struts>    

TestAction1.java里：

package com.xsl.action;

import com.opensymphony.xwork2.ActionSupport;

public class TestAction1 extends ActionSupport {
    private String name;
    public String test2(){
        System.out.println("重定向--action1--test2--name--"+name);//重定向--action1--test2--name--jack
        return "test2";
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    
}

success.jsp里顯示：---this is success.jsp  

 

二、跳轉到Action

index.jsp里：<a href="testAction1!test3?name=rose">請求轉發</a><br>

struts.xml里：

                tyoe="redirect"表示重定向到jsp
                type="chain"表示請求轉發至另一個action
             -->
            <result name="test3" type="chain">testAction2_test1</result>
        </action>
        <!-- struts2.1這個版本要求action在跳轉action時，不能寫死action的名字 -->
        <action name="testAction2_*" class="com.xsl.action.TestAction2" method="{1}">
            <result>/success.jsp</result>
        </action>

    </package>
</struts>
